I've said several time before that I hate bone claws and I'll tell you how I feel about this theory. My biggest problem with bone claws in this film has to do with Sabretooth and Wolverine's fight immediately after Silver Fox's death.
In the comics when this story was first told Wolverine didn't have any claws and he got the beating of his life. After Stryker said in X2 that Wolverine volunteered for the experiment we could assume that in the origin movie, an event like that would be Wolverine's motivation for going through the procedure.
The thing is though, when Wolverine found out he had bone claws, he was still able to defeat all of his enemies and his healing powers and senses were stronger than ever. So it's hard for me to imagine Wolverine losing to Sabretooth so incredibly bad with the bone claws that he would choose to get an adamantium skeleton. Sure breaking bones still hurts alot even when you can heal, but when your bone claws can already cut through metal and you can regrow bone, limbs, etc...it makes the adamantium seem not as important.
If Wolverine can't grow bone back, his claws and other bones break, he chooses to go through the procedure, then that might make alitte more sense. So I like this idea better, it sounds like an idea Claremont had for the character that Wolverine had broken all the bones in his body and he couldn't heal bone so had them replaced with adamantium. It also sounds a bit like Archangel's origin too.
So I kind of like that idea but at the same time I feel if they introduced the bone claws and made him lose them for good, why put them in at all?
